自适应UITableView的Cell高度问题

1.自己计算Cell的高度返回:

1>model中计算:

//
//  InfoModel.h
//  OCDemo

//

#import <Foundation/Foundation.h>

@interface InfoModel : NSObject

@property (nonatomic, copy) NSString *uid;
@property (nonatomic, copy) NSString *title;
@property (nonatomic, copy) NSString *desc;
@property (nonatomic, copy) NSString *headImage;

@property (nonatomic, assign) CGFloat cellHeight;

- (instancetype)initWithDictionary: (NSDictionary *)dic;

@end

//

#import "InfoModel.h"

@implementation InfoModel

- (instancetype)initWithDictionary: (NSDictionary *)dic {

    if (self = [super init]) {

        self.title = dic[@"title"];
        self.headImage = dic[@"img"];
        self.desc = dic[@"desc"];

        CGSize contentSize = [self.desc boundingRectWithSize:CGSizeMake(K_SCREEN_WIDTH - , ) options:NSStringDrawingUsesFontLeading | NSStringDrawingUsesLineFragmentOrigin attributes:@{ NSFontAttributeName: [UIFont systemFontOfSize:]} context:nil].size;
        self.cellHeight = contentSize.height + ;
    }
    return self;
}

@end

2.自定义CellFrame类存储Cell高度:

//
//  CellFrame.h
//  OCDemo
//
//  Created by 思 彭 on 16/12/28.
//  Copyright © 2016年 思 彭. All rights reserved.
//

#import <Foundation/Foundation.h>
#import "InfoModel.h"

@interface CellFrame : NSObject

@property (nonatomic, assign) CGRect headImgViewFrame;
@property (nonatomic, assign) CGRect titleLabelFrame;
@property (nonatomic, assign) CGRect contentlabelFrame;
@property (nonatomic, assign) CGFloat cellHeight;

@property (nonatomic, strong) InfoModel *model;

@end

//
//  CellFrame.m
//  OCDemo
//
//  Created by 思 彭 on 16/12/28.
//  Copyright © 2016年 思 彭. All rights reserved.
//

#import "CellFrame.h"

@implementation CellFrame

- (void)setModel:(InfoModel *)model {

    _model = model;
    _headImgViewFrame = CGRectMake(, , , );
    CGSize contentSize = [model.desc boundingRectWithSize:CGSizeMake(K_SCREEN_WIDTH - , ) options:NSStringDrawingUsesFontLeading | NSStringDrawingUsesLineFragmentOrigin attributes:@{ NSFontAttributeName: [UIFont systemFontOfSize:]} context:nil].size;
    _titleLabelFrame = CGRectMake(CGRectGetMaxX(_headImgViewFrame) + , , K_SCREEN_WIDTH -  - , );
    _contentlabelFrame = CGRectMake(, CGRectGetMaxY(_headImgViewFrame) + , K_SCREEN_WIDTH - , contentSize.height);
    _cellHeight = CGRectGetMaxY(_contentlabelFrame);
}

@end

2.使用第三方Masonry自使用行高:

很方便,要求自己把约束要设置完全!!!
